Really glad there’s finally a good book app out there, i’ve been waiting for something like this!” — scruffythejanitor01 “I love the UI of this app, easy to use and aesthetically pleasing. Also, I've been struggling getting back into reading and the screentime feature has helped me loads. I haven't been able to read this much since 4 years ago. Thank you Margins” — mitakaluvr “The search by vibes is so cool. I am a WWII buff, but this search popped up a two-book WWII saga I had never even heard of, much less read. It ended up being my top read of 2025.” —Michigancolt FREE TO USE Almost all features are free to use. An optional subscription unlocks premium features and priority support.
